ものである。(Prior art) When completely rolling a member having serration threads and threads with different rolling diameters, a serration rolling tool (1) and a thread rolling tool (2) are used as shown in Figures 1 and 2. They are arranged in parallel and the serrations and threads are rolled at the same time. For example, in JP-A-60-72630, the lead angle of the thread rolling tool is corrected to match the rolling circle diameter of the serrations and the specifications of the product shape.
しかし、該ねじ転造工具のリード角は微調整が不可能な
単体である。However, the lead angle of the thread rolling tool is a single unit that cannot be finely adjusted.

A pair of serration rolling tools (1) and a thread rolling tool (2) are moved in the entire longitudinal direction with the rolled objects αl having different rolling diameters rotatably supported by two fields and sandwiched above and below. , The serrations and screws on the same axis are all rolled on the outer peripheral surface of the object to be rolled at the same time. During rolling, the rolled object (
If an unreasonable force is applied in the axial direction due to the difference in the shape of 13 or the blade/shape, the thread rolling tool (2) will move slightly in the width direction with the entire center of the length of one rotation of the workpiece. The force that it takes? Absorb. Thus, as shown in Figs. 1 and 2, the rolled object (13) shown on the right side of the drawing (13) has serrations on the large diameter part and threads on the small diameter part at the same time, as shown on the left side. 0 (Example) Next, an example of the present invention will be described with reference to the drawings.A serration rolling tool (1) with a rack-shaped tooth profile formed in the same manner as before, and a thread rolling tool with a thread groove having a full lead angle as usual. Forming tools (2) The thread dies (2) are used to roll threads and serpentines on the outer circumferential surface of the object αJ, which is arranged in parallel and rotatably supported by the center (to).
) is placed on the tool holder (5), and its both ends are shown in FIG.
As shown in Fig. 5, it is attached by bolts (8) to a pair of attachments (31, (4)) fixed to the holder by poles (E). A flat cage (62 It is fixed with the bolt (8) through the base plate (7).On the other hand, the bottom surface (9) of the thread rolling tool (2) and the tool holder (

金用いることができる。On the side of the thread rolling tool (2) opposite to the serenoid rolling tool, the tool holder (5) is attached to the side cutting plate αQ by the bolt α force (see Fig. 3). Rolling tool (
2), as shown in Fig. 4, a disc spring Qυ is installed on the edge plate αG side of the near side of the finished end rib and on the four sides of the counterbore hole, respectively.1)
The thread rolling tool (2) is tightened to the side blade plate, but the thread rolling tool (2) is tightened in the width direction through the flat cage (6 pins) by the deflection of the disc spring QII. Slight movement is allowed.The load relative to the amount of deflection of the disc spring is smaller than the sword/blade load in the axial direction during rolling of the object to be rolled + J3, and the amount of deflection of the disc spring is not eliminated. Since the flat cage (6) allows smooth sliding contact with the underside of the tool holder (5J's upper electric wire rolling tool (2)), tetrafluoroethylene, etc. can be used instead of the flat cage.
